QUERY_ACCEL_OPTIONS (option 11), add V5 ONLY option

As documented below, QUERY_ACCEL_OPTIONS (option 11) provides two options only. Simply (for all accelerators) or (V7 only). Especially, for migrations projects from V5 to V7, if we had third option such as (V5 Only), this would secure the workload...

Need ability to load AOT while accelerator is stopped

IDAA - Logical Name - ACCEL_LOAD_TABLES support

Treat "ALTER TABLE ... ALTER COLUMN ROWID ... RESTART WITH ..." not as a schema change and do not require load of IDAA

"ALTER TABLE ... ALTER COLUMN ROWID ... RESTART WITH ..." is treated as a Schema Change and requires that the table be reloaded. This Alter is not a Schema Change, please don't require a reload after it is executed.
